Abstract

A door arrangement for opening and closing a motor vehicle door in a door opening (2) in an outside vehicle wall (1), having at least one door panel (3) which, in the closed position, assumes a position that is essentially flush position with the outside wall (1) and which can be swung into an open position which at least partially exposes the door opening, and in which the door panel (3), outside of the vehicle, assumes a roughly parallel position to outside wall (1). The door panel (3) is connected to the vehicle to swing via at least one pivoting lever (5). To enhance the sealing action in the closed position, it is provided that a forward edge (31) of the door panel (3), by way of a linkage mechanism (7, 8, 9) executes a movement by which this edge (31) fits from inside behind the associated edge (door frame 4B) of outside wall (1) or a seal (10) located thereon, in the closed position.

Claims

1. A motor vehicle door arrangement for closing a door opening in an outside wall of a motor vehicle, comprising at least one door panel which in a closed position assumes an essentially flush position with the outside wall and a pivoting drive having a pivoting lever for swinging the door panel into an open position in which the door opening is at least partially exposed, the door panel assuming a position roughly parallel to said outside wall;

wherein said pivoting drive comprises a linkage mechanism having means for causing a forward edge of the door panel, which is forward in a closing direction, to execute a movement by which said forward edge fits from the inside behind an associated part at an edge of the outside wall in the closed position, wherein said pivoting lever is connected between an axis of rotation which is fixed relative to the vehicle and an axis of rotation that is fixed at the door panel, and wherein said linkage mechanism is connected to the pivoting lever and to an axis of rotation on the door panel which is displaced from the axis of rotation on the door panel to which the pivoting lever is connected.

2. Motor vehicle door arrangement according to claim 1, wherein said associated part is a door frame of the outside wall.

3. Motor vehicle door arrangement according to claim 1, wherein said associated part is a seal located on an edge of the outside wall.

4. Motor vehicle door arrangement according to claim 1, wherein said associated part is a lock part located on a chassis of the vehicle in an area of an edge of the outside wall.

5. Motor vehicle door as claimed in claim 1, wherein said pivoting lever is driven via a rotary shaft which also at least indirectly drives said linkage mechanism.

7. Motor vehicle door as claimed in claim 2, wherein said pivoting lever is connected in a central area of the door panel and has an approximately right-angle bend.

8. Motor vehicle door as claimed in claim 1, wherein said linkage mechanism includes means for locking the door panel in the closed position.

17. Motor vehicle door as claimed in claim 1, wherein said distance between the axes of rotation on the door panel is a fixed distance.

6. Motor vehicle door arrangement for closing a door opening in an outside wall of a motor vehicle, comprising at least one door panel which in a closed position assumes an essentially flush position with the outside wall and a pivoting drive having a pivoting lever for swinging the door panel into an open position in which the door opening is at least partially exposed, the door panel assuming a position roughly parallel to said outside wall;

wherein said pivoting drive comprises a linkage mechanism having means for causing a forward edge of the door panel, which is forward in a closing direction, to execute a movement by which said forward edge fits from the inside behind an associated part at an edge of the outside wall in the closed position;

wherein said pivoting lever is driven via a rotary shaft which also at least indirectly drives said linkage mechanism; and

wherein the linkage mechanism has an auxiliary pivoting lever coupled near a front edge of the door panel, a connecting rod which is connected to the auxiliary pivoting lever and which is pivotable around an axis of rotation that is fixed relative to the vehicle, and a coupler joining the connecting rod to a joint on the pivoting lever.

9. Motor vehicle door as claimed in claim 6, wherein the connecting rod is an angular lever having a shorter side and a longer side;

and wherein the coupler is connected to the shorter side of the angular lever and the auxiliary pivoting lever is connected to said longer side.

10. Motor vehicle door as claimed in claim 6, wherein the pivoting lever has a shoulder which is eccentric relative to the rotary shaft and on which a joint for connection of the coupler to the pivoting lever is located.

11. Motor vehicle door as claimed in claim 6, wherein the coupler of the linkage mechanism is guided by a guide pin in a crank located near the rotary shaft.

12. Motor vehicle door as claimed in claim 10, wherein the coupler of the linkage mechanism is guided by a guide pin in a crank located near the rotary shaft.

13. Motor vehicle door as claimed in claim 11, wherein the crank has a slanted section and an arc-shaped section which is concentric to the rotary shaft.

14. Motor vehicle door as claimed in claim 13, wherein the pivoting lever is driven via a cam connected to the rotary shaft.

15. Motor vehicle door as claimed in claim 12, wherein the pivoting lever is driven via a cam connected to the rotary shaft.

16. Motor vehicle door as claimed in claim 14, further comprising a stop provided on the pivoting lever;

wherein the cam, during opening of the door panel, runs against said stop and causes the stop to rotate after the guide pin has reached a transition from the slanted segment to the arc-shaped segment of crank.

18. A motor vehicle door arrangement for closing a door opening in an outside wall of a motor vehicle, comprising at least one door panel which in a closed position assumes an essentially flush position with the outside wall and a pivoting drive having a pivoting lever for swinging the door panel into an open position in which the door opening is at least partially exposed, the door panel assuming a position roughly parallel to said outside wall;

wherein said pivoting drive comprises a linkage mechanism having means for causing a forward edge of the door panel, which is forward in a closing direction, to execute a movement by which said forward edge fits from the inside behind an associated part at an edge of the outside wall in the closed position, wherein said pivoting lever is connected between an axis of rotation which is fixed relative to the vehicle and an axis of rotation that is fixed at the door panel, and wherein said linkage mechanism is connected to move about the fixed axis of rotation of the pivot lever with rotation of the pivoting lever.
